Solubility of carbon dioxide in aqueous solutions of diisopropanolamine and methyldiethanolamine

Thermodynamic modeling of CO2 and H2S solubilities in aqueous DIPA solution, aqueous sulfolane–DIPA solution, and aqueous sulfolane–MDEA solution with electrolyte NRTL model

“…The predictions are considered satisfactory. Table 15 summarizes the available experimental VLE data for CO 2 and H 2 S and the acid gas mixture in aqueous DIPA solution [43][44][45][46]. The VLE data for the H 2 O-DIPA-CO 2 ternary system cover DIPA concentration from 10 to 35 wt% and CO 2 loading up to 1.31.…”

Experimental and Modeling Study of the Phase Behavior of (Methane + CO2+ Water) Mixtures

“…The binary systems (CO 2 + CH 4 ), − (CH 4 + H 2 O), ,− and (CO 2 + H 2 O) ,,,,− have been covered extensively in the literature, both in terms of experimental phase equilibrium data and modeling approaches. A thermodynamic model developed by Duan et al , for the solubility of CO 2 in water at temperatures of (273 to 533) K and pressures of (0 to 200) MPa was able to represent the CO 2 solubility data considered almost to within the experimental uncertainties.…”

Solubility and thermodynamic modeling of hydrogen sulfide in aqueous (diisopropanolamine+2-amino-2-methyl-1-propanol+piperazine) solution at high pressure

“…Thus, knowledge of the solubility of the acid gases in blended amines is necessary in the design of industrial gas absorption units. However, most of the equilibrium data is devoted to the solubility of CO 2 [15][16][17][18], and less data are available for H 2 S solubility particularly in blended alkanolamines. The several works [19,20] for solubility of H 2 S in alkanolamines are given as follows.…”
